In Grid Manager, you can use the IPv6 Net Map (network map) and List panels to manage your IPv6 network infrastructure. After you select a network container from the IPAM tab, Grid Manager displays it in the Net Map panel, by default. The Net Map panel provides a graphical view of your networks and has a number of features that simplify network management. The List panel displays the networks in table format.
You can always switch your view of a network container between the Net Map and List panels. Grid Manager keeps track of which panel you last used. When you select a network container, Grid Manager displays it in the Net Map or List panel, depending on which one you last used. For information about each panel, see IPv4 Network Map on page 607 and IPAM Home .
You can use Grid Manager to manage IPv6 networks and their AAAA, PTR and host resource records. You can configure IPv6 netw

orks and track IP address usage in those networks. You can also split and join IPv6 networks, when necessary.

IPv6 Network Map

After you select an IPv6 network container from the IPAM tab, Grid Manager displays it in the IPv6 Net Map (network map) panel, by default. Just like the IPv4 Net Map, the IPv6 Net Map provides a high-level view of the network address space. You can use Net Map to design and plan your network infrastructure, and to configure and manage individual networks.
The Net Map panel presents a complete view of the network space, including the different types of networks that are in it and its unused address space. IP addresses that belong to a network are blocked off. Each color-coded block represents a network container, a leaf network, or a block of networks that are too small to be displayed individually in the map. For example, in a /64 or /96 network, networks smaller than /76 or /108 respectively and that are beside each other are represented as a multiple network block. In addition, the fill pattern of the blocks indicates their utilization. Therefore, you can quickly evaluate how many networks are in a network container, their relative sizes, utilization, and how much space you have left.

...


As you mouse over areas of the map, it displays IP information about the area. Net Map also has a zoom feature that allows you to enlarge or reduce your view of a particular area.
Figure 13.9 displays the network map of a 1111::/16 network, which is a network container that has network containers and leaf networks.

Displaying Network Information
As shown in Figure 13.9, as you mouse over the map, Net Map displays IP information about the area. When you mouse over an unused area, Net Map displays the following information:

  • The start and end IP address
  • The largest possible network
  • The number of /64 networks that can fit in that space

...

When you mouse over a network, Net Map displays the following information:

  • Network address and netmask

...

  • The first and last IP address of the network

...

  1. Right-click and select Zoom In, or click the Zoom In icon in the Net Map task bar. The pointer changes to the zoom in selector.
  2. Select a starting point and drag to the end point. The starting point can be anywhere in the map. It does not have to be at the beginning of a network.
    Net Map displays a magnified view of the selected area after you release the mouse button. As you mouse over the zoomed in area, Net Map displays IP information about it.
  3. You can do the following:
    • Select an area and zoom in again.
    • Add a network. If you zoom in on an area and click Add without selecting an open area first, Net Map selects the area where it can create the biggest possible network in that magnified area.
    • Select a network and perform any of the following operations:
      • Edit its properties.
      • Open it to display its IP List.
      • Delete it immediately, or schedule its deletion.
    • Right-click and select Zoom Out, or click the Zoom Out icon in the Net Map task bar. Each time you click Zoom Out, Net Map zooms out one level and the Zoom Controller is updated accordingly.

    • If you select one or more networks in the List view and then switch to the Net Map view, the first network is also selected in Net Map. Although, if you select a network in the List view that is part of a Multiple Networks block in Net Map, it is not selected when you switch to the Net Map view.

...

  1. Do one of the following:
    • Click the Add icon.
      Net Map displays the netmask slider and outlines the open area that can accommodate the largest network.
    • Select an open area, and then click the Add icon.
      Net Map displays the netmask slider and outlines the largest network that you can create in the open area that you selected.
  2. Move the slider to the desired netmask. You can move the slider to the netmask of the largest network that can be created in the open area. You can also move the slider to the smallest network that can be placed in the current zoom level of Net Map.
    As you move the slider, Net Map displays the netmask. The outline in the network map also adjusts as you move the slider. When you mouse over the outline, it displays the start and end address of the network.
  3. After you set the slider to the desired netmask, you can drag the new network block around the open area to select a new valid starting address. You cannot move the block to a starting address that is invalid.
  4. Click Launch Wizard to create the network.
    The Add Network wizard displays the selected network address and netmask.
  5. You can add comments, automatically create reverse mapping zones, and edit the extensible attributes. (For information, see Adding IPv6 Networks217.)
  6. Save the configuration and click Restart if it appears at the top of the screen. Grid Manager updates Net Map with the newly created network.

...

  1. Select a network or area.
  2. Click the Open icon.
    • If you selected a network container, Grid Manager displays it in the Net Map panel. You can drill down further by selecting a network or open area and clicking the Open icon again.
    • If you selected a block of multiple networks, Grid Manager displays the individual networks in the Net Map panel. You can then select a network or open area for viewing.
    • If you selected a leaf network, Grid Manager displays it in the Network List panel.
    • If you selected an open area, Grid Manager displays an enlarged view of that area in the Net Map panel.
      This is useful when you are creating small networks in an open area

You can sort the list of subnets in ascending or descending order by columns. For information about customizing tables in Grid Manager, see Customizing Tables.
You can also modify some of the data in the table. Double click a row of data, and either edit the data in the field or select an item from a drop-down list. Note that some fields are read-only. For more information about this feature, see Modifying Data in Tables.

Tip: If you select a network from the list and switch to the Net Map panel, the network is also selected in the network map.

Filtering the Network List

You can filter the network list, so it displays only the networks you need. You can filter the list based on certain parameters, such as network addresses, comments and extensible attributes. When you expand the list of available fields you can use for the filter, note that the extensible attributes are those with a gray background.

  1. From the Data Management tab, select the IPAM tab -> network check box, and then click Split from the Toolbar.
  2. In the Split Network editor, do the following:
    • Address: Displays the network address. You cannot modify this field.
    Netmask
    • Net mask: Specify the appropriate netmask for each subnet.
    • IPv6 Prefix Collector Network: If you split a network with prefix delegations that are not tied to specific addresses, specify the network in which all prefix delegations are assigned. If you leave this field blank, the server assigns all prefix delegations that are not tied to specific addresses to the first network.
    • Immediately create: Select one of the following:

...

      • Only networks with ranges and fixed addresses: Adds only the networks that have DHCP ranges and fixed addresses.
      • All possible networks: Adds all networks that are within the selected netmasks. You can select this option only when you increase the CIDR by 8 bits.
    • Automatically create reverse-mapping zone: Select this check box to have the appliance automatically create reverse-mapping zones for the subnets. This function is enabled if the netmask of the network is a multiple of four, such as 4, 12 or 16.
  1. Click OK.
